"...looks like a Bison copy. The headstock design looks like Bruno. The pickups are the same as the Kent 720 series - their topline guitars. I suspect this came out of the Kawai factory because they produced Bruno, Kent and Teisco guitars."

Interesting features include the two plates on the headstock matching the plate the pickups are sitting on; separate plates for pickups and controls; the German carve around the top of the instrument's body; and, of course, the four pickups and attendant switches (my guess is that the switch near the volume and tone pots selects between the front and rear pair of pickups, whilst the two toggles near the lower horn are 3-way selectors for each pair).
